RE: A380 status
Parts are being built.
Rumor has that at this stage of the design the plane is overweight. Design must go on a diet.
5000 PSI hydraulics will be used versus the standard 3000 PSI to reduce weight of actuation systems. Hydraulic power units will be less centralized to reduce heavy hydraulic tubing runs.
My boss who has his sources says wing to body join remains a design problem. More composites may have to be introduced to complete the A380 diet.

The pictures are from a maximum energy RTO (Refuse Take Off test). They use worn brakes, accelerate to take off speed, then apply brakes and spoilers, no thrust reversers. No landing involved. I don’t believe the airplane exceeds MTOW (Maximum Take off weight)(365 tonnes)in these tests. They don’t want to destroy a perfectly good airplane, not to mention produce bad PR.

Wait a minute! You are barking up the wrong tree when you claim US protectionism will prevent low cost carriers from the UK getting established in the US. Do you see any low cost US carriers in Europe? I don’t think so.
The cost of getting all the infrastructure established,(maintenance, facilities, etc)would immediately put any foreign operation in the hole from a cost basis. Buying a hub and spoke carrier with a bleak financial picture like US Airways won’t help either given the typical point to point operation of a low cost carrier.
Southwest and Alaska Airways have been in a pitched low cost battle on the west coast of the US for years. Now they are moving to the eastern US. These airlines are masters and I mean masters at keeping costs down. Most new low cost carriers will be caught in a buzz saw trying to compete with them.
I may be wrong, but even Jet Blue’s cost structure looks too expensive. For instance Direct TV for free. It’s just another system to break down. And current entertainment systems do break down. When Jet Blue gets a little age on those systems and Jet Blue’s maintenance costs and airplane down times go up. I look for trouble at Jet Blue, especially if they cross paths with SWA in the future.
RE: 5 engines on BA 747
Dazza,
You are correct. That 747 carries a fifth engine for testing purposes. Boeing uses it to test engines for new airplanes. The extra engine strut is inboard of all the existing four engines. The plane is the original 747, alias “The City of Everett”. I work a couple of km’s from where the plane is based.
